To all whom it may concern:

Be it known that I, JACOB SOHAUB, a citizen of the United States, and resident of Lawrenceburg, in the county of' Dearborn and State of Indiana, have invented certain new and useful Improvements in Mixing- Mills, of which the following is a specification.

This application is a divisionof my app Pcation for artificial fuel machine filed ay 28th, 1919, Serial No. 300,364.

In my said application Ihave set forth improvements in machines adapted to mix and. combine together different materials during their flow through the machine, such as for the production of artificial fuel comprising a combustible body portion containing an inflammable substance, such as alcohol.

My present invention has reference to improvements set forth in my aforesaid application adapted to commingle and mix together different materials during their flow, such as a body portion of suitable composition and consistency and a fluid to be commingled therewith, whereby the resulting mixture may be used for any desired purposes.

In accordance with my invention a colloid may be mixed with alcohol foruse in the production of an artificial fuel, such for instance as the artificial fuel set forth in Letters Patent to me No. 1,262,267, issued A ril9, 1918. p

y invention comprises novel details of improvement and combinations of parts that will be more fullyhereinafter set forth and then pointed out in the claims.

Reference is had to the accompanying drawings forming part hereof, wherein- I Figure 1 is a front view of a machine embodying my invention;

Fig. 8 is a plan view of a distributing melmber for the material shown in Fig. 2; an

Fig. 9 is a side view partly in section on the line 99 in Fig. 8.

Similar numerals of reference indicate corresponding parts in the several views.

A suitable frame or support is indicated at 1 adapted to sustain the various parts of the machine, and a feed pipe indicated at 2 is adapted to be connnected with a tank or other suitable source of supply (not shown) from which a flowing material or composition may be fed, such as a colloid of desired composition. A suitable valve is indicated at 3 to control the flow of material. Air pressure may be maintained in said tank to force said material through pipe 2. Said pipe 2 communicates through fitting 4 with a pump 5 which may be of any suitable construction, which may be a gear pump. From said pump a pipe 6 com municates with a branch 7 of ahead or casing 8 for delivery of the said material or colloid to means for mixing it with a flowing substance, as alcohol, such as ethyl alcohol; The. shaft 5 of pump 5 may be provided with a gear 9 to mesh with worm 10 on a drive shaft 11 operated by a belt 12 on pulley 13 driven from any suitable source of power, whereby said material or colloid may be continually fed to head 8. Said head is shown comprised in two members 8, 8" providinga chamber 14 (Fig. 2)

to receive the saidmaterial or colloid, which members may be secured together by screw threads. A conduit member 15 is shown fitted to member 8 by screw threads and provided with a central passage 15 and with lateral passages 15, provided between upstanding lugs 15 on member 15 and communicating with chamber 14 on opposite sides of passage 15 whereby the said material or'colloid from chamber 14 will be distributed into passage 15 from different sides, IVithin passage 15 is a feed worm 16 (Figs. 2 and 5). carried by a shaft 17 whose upper portionis provided with bore 17 to receive and distribute a flowing substance such as alcohol. The upper portion of shaft 17 is rotative in a bearing 18 having a gland 18, shown confined within head 8 by means of .a cap 19 shown secured to said head by screw threads, suitable packing making tight joints where required. A T-coupling 20(Fig. 1) is shown secured by nipple 21 and union nut 22 with cap 19 (Fi 2). A pipe 23 is ada ted to, supply sai substance or ethyl alco 01 through parts 20, 21 to bore 17 of shaft 17, and I have shown a pump 5 for said substance or alcohol, which may be similar to pump 5, communicating with pipe 23 and having its drive shaft connected to drive gear 9. The said substance or alcohol may be supplied from filter 24 through pipe 25 having a valve 26 to control the flow to pipe 23. Air pressure may be maintained on the said sub stance or alcohol flowing from a supply tank to the filter 24 if desired. The said material or colloid from passage 15 is fed through conduit 27, which is a continuation of conduit 15, (Figs. 1, 2 and 4). that is shown connected by a nut 27 with conduit 15, which conduit has a series of inwardly extending projections 28 shown projecting from a wall into the bore of said conduit. I have shown series of circularly disposed projections 28 spaced apart in said conduit, and shaft 17 is provided with correspondingly disposed angularly arranged fins or projections 29 operable rotatively between the several series of projections 28 (Figs. 2 and 6). For convenience of manufacture the fins or projections 29 are adapted to be formed upon sleeve 30 secured to shaft 17 (Figs. 2, 6, 7). The projections 28 may be in the form of pins driven into holes in conduit 27 after sleeve 30 with shaft 17 is assembled in said conduit. The said fins or projections 29 are shown disposed in such angular position respecting the axis of shaft 17 as to force the colloid within conduit 27 downwardly and against pins or projections 28. Shaft 17 is provided with laterally disposed holes 17 communieating with corresponding holes 30 in sleeve 30 for delivering alcohol from bore 17 into conduit 27. Shaft 17 is shown journaled at its lower portion in bearing 31 in conduit 27, a gland 32 affording a tight joint to prevent the escape of the mixture of said material and substance, which shaft is shown provided with a pulley 33. Head 8 is attached to frame 1 by bracket 34 and conduit 27 is shown attached to said frame by bracket 35 (Fig. 3) Pulley 33 receives belt 36 shown passing over idle pulleys 37 carried by frame 1 and driven by a pulley on shaft 17. When said material or colloid is admitted to chamber 14 and said substance or alcohol is admitted to shaft 17 said shaft will be rotated whereupon the material or colloid will be forced through conduit 27 and the said substance or alcohol will pass through holes 17", 30 into said conduit, wherein the same will be intimately commingled by the rotation of the projections 29 which serve to carry the mixture around and force it into contact with projections 28. The mass or mixture so formed will be forced from conduit 27 through the passage 39 which may be controlled by a suitable valve 40. The said mass or mixture may be conducted through an instrumentality 41 where it may be charged with other material such as alcohol from pipe 42 communicating with a supply source or filter 43, as set forth in my aforesaid application, or said mass or mixture may be utilized in an other desired \va 11 order to clean t e interior of the various parts described from the residue material or colloid at any time when the machine is stopped, I have illustrated a filter 44 which may contain methyl alcohol andwhich may be maintained under air pressure in a supply tank which filter is shown connected by pipe 45 with fitting 4 and controlled by a valve 46; pipe 47 connects filter 44 through valve 48 with coupling 20 and pipe 49 through valve 50 connects said filter with instrumentality 41.

The aforesaid materials or colloid, say comprising cellulose pentanitrate and ethyl alcohol, such as referred to in my aforesaid Letters Patent No. 1,262,267, is fed continuously by means ofpump 5 into conduit 27, and a flowing substance, such as ethyl alcohol in suitable proportion controlled by the operation of pump 5 is simultaneously fed to said conduit through holes 17 of shaft 17 During the rotation of said shaft said substance is thoroughly commingled with said material or colloid, the operation of the projections 29 within such mass of material causing the re uired agitation thereof to effect the desire commingling of said substance with said flowing materlal Whereby the desired viscosity may be produced. Said mixture thence passes from conduit 27 for use as before specified. The operation of producing the mixture of the materials is continuous in the machine, since the main requirements are to keep the tanks supplied with requisite materials and maintain the operation of the pumps and the other moving parts of the machine while the materials flow and are assembled and commingled in the manner set forth.

My invention is not limited to the partic.ular details of construction set forth and may be varied within the scope of the appended claims without" departing from the spirit of my invention. It will be understood that any suitable materials may be mixed and combined together during their flow to be passed through the machine.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. The combination of a conduit having an inlet and an outlet, a tubular shaft rotative therein and having holes for the flow of material from the shaft into the conduit, and means to supply said shaft with fluid, means to rotate the shaft, said shaft having space in the material in the conduit.
